9.4.2 USB Endpoint Interrupt Enable register (USBEpIntEn - 0xFFE0 C234)
Setting a bit to 1 in this register causes the corresponding bit in USBEpIntSt to be set
when an interrupt occurs for the associated endpoint. Setting a bit to 0 causes the
corresponding bit in USBDMARSt to be set when an interrupt occurs for the associated
endpoint. USBEpIntEn is a read/write register.
